Unfortunately, we are not dealing with a unique case. It is quite common to come across software of this type, created solely to defraud. In many cases it goes unnoticed, so the victim does not find out that she has a virus of this type until it is too late and her passwords or personal data have been stolen.

The sum of all of them has reached 2.5 million downloads. They supplant original applications, such as Android’s own calendar. Other fake apps found have been TV/DMB Player, Music Downloader and News.
But, what happens if you have one of these programs installed? The app will remain without giving signals for several weeks. They do this so as not to arouse suspicion. From there, start your fraud activity. What they do is display advertising, even if the screen is off. A clear example of adware, which can melt the phone’s battery.
They do this since, in the installation process, they are going to ask the victim to allow that app to run in the background, something that is going to mean that it uses processor, memory, network resources, etc. It will allow this fake application to run with the screen turned off, without the need for the mobile to be unlocked. You will be constantly consuming resources.
As indicated from McAfee, the ads disappear as soon as the screen is turned on. However, it is possible that, for a short time, they can be seen right when you turn it on. What the attackers are looking for is not to arouse suspicion, since if the victim sees that ads appear constantly, she could investigate what is happening.
